ABSTRACT We report an extremely rare tumor presenting with myoid features in the left cerebellum lobe in a 62-year-old man. This tumor consisted of medium to large round cells with focal lipomatous and myoid differentiation. Immunohistochemically, the tumor cells expressed synaptophysin, GFAP (glial fibrillary acidic protein) and focally desmin. From these findings, we concluded that this tumor was a liponeurocytoma with myoid features. To our knowledge, this is the second report of liponeurocytoma with myoid differentiation in the cerebellum.
